Big companies have a steady stream of legal cases with questionable merit. The lawyers start the case and then try to make it look like it will be a long and difficult battle with a lot of legal work (discovery, etc) attached.
The goal is to get the company to offer a monetary settlement to make the case go away. If you can inflate the difficulty of the case such that it would incur huge amounts of legal work for the company to disprove it, they might calculate that it’s cheaper to offer the person $20,000 than to spend $40,000 of lawyer salaries for a team of people to handle it.
Some of the stories I heard from corporate legal people were crazy, like people forgetting that there were cameras in the building and trying to bring cases that were easily contradicted by reviewing the recordings.
As far as I can tell the limiting factor on these cases is people being afraid of expensive lawyer costs if they lose. If AI removes the lawyer costs from the equation and people start blasting companies with frivolous lawsuits with ChatGPT driving the case, I could see this becoming a real problem.
